Once the core pf a star has turned to iron, it can burn no longer. The star collapses by its own gravity and the iron core heats up. The core becomes so tightly packed that protons and electrons merge to form neutrons. In less than a second, the iron core, which is about the size of Earth, shrinks to a neutron core with a radius of about 6 miles (10 kilometers). The outer layers of the star fall inward on the neutron core, thereby crushing it further. The core heats to billions of degrees and explodes (supernova), thereby releasing large amounts of energy and material into space. The shock wave from the supernova can initiate star formation in other interstellar clouds. The remains of the core can form a neutron star or a black hole depending upon the mass of the original star.
-How Stars Work-
In India iron is believed to repel the Djinn and other evil spirits; in Scotland, Ireland and Europe iron keeps away mischievous and malicious fairies. In other parts of the world iron is said to keep away ghosts.
Iron. It's just not a the most common element on Earth. It's got a fun story too.
